column

It identifies the column to which you want to apply the formula. Multiple attributes can be specified, as long as they’re enclosed in double brackets. The column parameter is mandatory.

group

It allows you to group the results by a certain column.

column1

It identifies the column to which you want to apply the formula. The column 1 parameter is mandatory.

column2

It identifies the column to which you want to apply the formula. The column2 parameter is mandatory.

• In the example here, we want to fill the min attribute with the minimum of the writing score attribute.

• We type the following formula:
  min($"writing score")
  and the function returns the lowest value for the writing score.

• If we want to group our results by their reading score, the formula will be:

• min($"writing score",$"reading score") and the function returns the lowest value for the writing score, grouped by the reading score.

• So the results will be:

  • The minimum writing score value associated with the 72 reading score is 59.

  • The minimum writing score value associated with the 90 reading score is 82.

When the column value is a list enclosed in double brackets, the formula considers the single rows of the attributes, so it calculates the minimum considering the chosen attributes in rows.

The formula will be: min(($"writing score",$"reading score"))

The results can be read as follows:

• For the student in row 1, the minimum value between the writing score and the reading score is 72, which is the reading score.

• In row 2, the minimum value between the writing score and the reading score is 88, which is the writing score.

• In the example here, we want to compare the writing score and the reading score, and we want to retrieve the lowest value between them.

• We write the following formula:
  min2($"writing score",$"reading score")

• The results are as follows:

  • In row 1, the minimum value between the writing score value (74) and the reading score value (72) is 72.

  • In row 2, the minimum value between the writing score value (88) and the reading score value (90) is 88.

and so on.
